I disagree with the premise you're basing the rest of your argument on. I would sooner say that a successful career in general (and engineering is no different) probably only hinges marginally on some intangible measure of aptitude (rephrased: aptitude is necessary but insufficient), and mostly results from some combination of coming from a privileged background (that is, encouraged from a young age that you're capable, exposed to good education, validation, having access to a professional network, etc.) and having had opportunity to thrive (for example, a lack of financial stress allowing one to pursue a risky business venture as opposed to having had to support one's family from a young age and therefore accepting a menial job straight out of high school).
Of course, one can find examples of people from underprivileged backgrounds succeeding in the sense you're referring to, but i don't for one second believe that simply "working hard" and "making the right choices" is enough to magically rise to the top of the economic dogpile. In essence, i think your statement is an instance of the just world fallacy (https://en.wikipedia.org/wiki/Just-world_hypothesis).
I've tried to be measured and objective in my reply, but i see this as a common myth that deserves to die, so my apologies if i'm sounding abrasive.

That sounds like wishful thinking.
How do you counter the following data points that suggest the opposite:
1. Software development contains a disproportionate number of successful Indians who come from much less privilege than the average American.
2. Despite having strong social safety nets European countries do not dominate tech.
Even in these countries underprivileged migrants without access to the safety nets are disproportionately successful.
Inside of the areas where external, natural forces are available to distinguish between sides of debates, no bias is necessary to form friendships or alliances. If you find yourself on the wrong side you can switch, and it won't be "disloyal" or "traitorous" because you'd be doing it to align yourself with something that isn't artificial. (For example, knowing the correct laws of physics instead of the wrong ones.)
